mVolt+ v0.36 Unlocks Advanced Power and Voltage Controls for NVIDIA RTX 50-Series GPUs

The latest update to mVolt+, version 0.36, introduces a suite of advanced power and voltage management features for NVIDIA RTX 50-series graphics cards. Notably, these new capabilities allow users to bypass the default power limits on select GPUs without resorting to traditional hardware modifications such as shunt mods or flashing a new vBIOS. This development marks a significant step forward for enthusiasts seeking to push their hardware beyond factory specifications.

Record-Breaking Overclocks Achieved Without Hardware Mods

Following the release of mVolt+ v0.36, users have reported impressive overclocking results. One Reddit user from the r/Overclocking community shared their experience with the NVIDIA GeForce RTX 5090, achieving a total power draw of 700 W—an increase of 125 W over the card’s standard 575 W TDP. During a 3DMark Steel Nomad benchmark, the GPU reached a peak clock speed of 3,127 MHz, which is 720 MHz higher than the reference clock of 2,407 MHz. The benchmark run resulted in a score of 16,523 points, highlighting the performance potential unlocked by the new software features.

Another enthusiast, as reported by VideoCardz, managed to overclock an ASUS ROG Astral NVIDIA GeForce RTX 5080 OC to draw 680 W, compared to its default TDP of 400 W (or 450 W when using official tools). This was accomplished without any shunt mod, relying solely on the new mVolt+ controls. Under these conditions, the ROG Astral RTX 5080 OC achieved a clock speed of 3,390 MHz during a FurMark burn test, while the card typically boosts to 2,760 MHz without overclocking.

Safety Concerns Over High Power Draw

The substantial increases in power draw have sparked discussions regarding the safety of the 12v-2×6 power cable, which is already known to face durability challenges at stock settings. The elevated TDPs achieved through software alone raise questions about the long-term reliability of power delivery components, especially as users push their GPUs to new limits. As always, caution is advised when experimenting with overclocking and power adjustments, particularly with high-end hardware.
